Very simple optimization problem
# The wreck of a plane in a desert is 15 miles from the nearest point A on a straight road.
# A rescue truck starts for the wreck at a point on the road that is 30 miles distant from A.
# If the truck can travel at 80 mph on the road and at 40 mph on a straight path in the desert,
# how far from A should the truck leave the road to reach the wreck in a minimum time?
